Description

Cleaning or hydrophilization treatment composition

The present invention relates to a cleaning or hydrophilizing agent composition and a method for cleaning or hydrophilizing a hard surface.

Background Technology Anionic surfactants are excellent in detergency and foaming properties, and are widely used as components of detergents. As one of the anionic surfactants, an internal olefin sulfonate obtained by using an internal olefin having a double bond inside instead of the end of the olefin chain as a raw material is known. The internal olefin sulfonate can be obtained, for example, by reacting the internal olefin with a gaseous sulfur trioxide-containing gas to sulfonate, neutralizing the obtained sulfonic acid, and further hydrolyzing the obtained sulfonic acid. Internal olefin sulfonates are known to have good biodegradability.

Further, conventionally, as a method of imparting antifouling property and decontaminating property to a hard surface, a method of hydrophilizing treatment is known. When the hard surface is hydrophilized, that is, the contact angle of the hard surface with water is lowered to make the hard surface wet easily with water, the dirt adhering to the hard surface after the treatment can be easily removed during cleaning. In addition to being expected to prevent recontamination of dirt, antifogging effect of glass, mirrors, etc., antistatic, prevention of frost formation of aluminum fins of heat exchangers, antifouling property of bathtub and toilet surface, decontamination Etc. can be expected.

A mixture of 100 g of beef tallow, 100 g of soybean oil, 2.5 g of monooleic acid, 1.0 g of Sudan III (manufactured by Wako Pure Chemical Industries, Ltd.), and 600 mL of chloroform was used as a model stain. The prepared model stains were uniformly applied to both sides of a 76 mm × 26 mm slide glass (S2441 manufactured by Matsunami Glass Industry Co., Ltd.) so that the total of both sides was 0.04 g, and the slide glass was prepared as a model oil-contaminated slide glass.
For washing, calcium chloride and magnesium chloride were added to deionized water at a mass ratio of 2: 1 to prepare water having a hardness of 8 ° dH. The washing or hydrophilizing treatment agent compositions shown in Tables 1 to 4 were mixed with 0.7 L of the prepared water to prepare a treatment liquid. The components (A) and (B) in the treatment liquid were mixed so as to have a total concentration of 0.023% by mass. Using a leanut tester, 0.7 L of treatment liquid and 6 pieces of model oil-contaminated slide glass (S2441 manufactured by Matsunami Glass Industry Co., Ltd.) were set in a 1-liter glass beaker for a cleaning test. The temperature of the treatment liquid was set to 30 ° C., and the mixture was stirred at a stirring speed of 250 rpm for 3 minutes and washed. The washed slide glass was transferred to a beaker containing 0.7 L of 8 ° dH water, rinsed at a stirring rate of 250 rpm for 1 minute, and dried at room temperature.
The cleaning rate of the model oil-contaminated slide glass obtained in the above cleaning test was calculated from the following formula. The values in Tables 1 to 4 are the average values of the cleaning rates of 6 sheets.

The treatment temperature was kept constant at 25 ° C., and the solution was mixed with a bioshaker at a stirring rate of 70 rpm for 15 minutes. Next, one 26 mm × 76 mm glass plate (manufactured by Akebono Trading Company) was added, and the mixture was stirred at a stirring rate of 70 rpm for 15 minutes. After stirring, the washing water in the tapper was drained, and 0.5 L of water having a new hardness of 8 ° dH was added to the tapper for rinsing, and the tapper was stirred at a stirring rate of 70 rpm for 1 minute for rinsing. After rinsing twice, the glass plate subjected to the hydrophilization treatment was dried overnight at room temperature.
The contact angle of water in the dried glass was measured using an automatic contact angle measuring machine (DM-501Hi). The values in Tables 1 to 4 are the average values of the contact angles of the three points. The contact angle of the glass before the hydrophilization treatment is 32.9 °.
